You can use string substitution. But note that your inlist() call will not do what you want: IBO is at position 2 in the list ttt, but in position 3 in the regression list. So you want something like: <hansl> open denmark list ttt = const LRY IBO string astr sprintf astr "%d", inlist(ttt,IBO) ols LRM ttt restrict b[@astr]=1 end restrict </hansl> Allin Cottrell
